The dynamic performance of a railway track subjected to moving trains depends strongly on
track support conditions. In reality, even for the well-constructed and well-maintained tracks …

High-speed railways are very important in global transportation. However, the railway
subgrade is significantly affected by the environment due to its exposure to the atmosphere …

The violent vibration and excessive settlement of trackbeds under high-speed train moving
loads are the main problems of ballasted tracks encountered in practice, which limits the rise …

Under high-frequency impact loading, the ballast bed is prone to ballast crushing,
deterioration, and other adverse effects. The use of elastic sleepers is an effective way to …

Tamping is an effective maintenance measure for ballasted track, but it can also cause
ballast breakage and sleeper abrasion. To balance the advantages and disadvantages of …

Geogrid reinforcement is a feasible technique for improving the mechanical and deformation
behaviors of calcareous gravelly sand that is predominantly distributed in reclaimed …

Cyclic load is widely adopted in laboratory to simulate the effect of train load on ballast bed.
The effectiveness of such load equivalence is usually testified by having similar results of …

This paper presents the results of Discrete Element Modelling (DEM) which quantitively
examine the effect of coal fouling on the deformation and degradation of ballast upon cyclic …

Ballast bed deformation is significantly influenced by its internal stress state. However,
investigations concerning ballast bed deformation focus mainly on the deformation …

The dynamic wheel-rail contact forces resulting from the interaction between vehicle and
track are responsible for the local track settlement. If these local settlements vary along the …
